CSS CSS Basics (2014) Understanding Values and Units Styling the Intro Paragraph

In the CSS basics course I can not move on from Challenge Task

In the CSS basics course I can not move on from this question: In the style sheet, select the intro class and add a font-size property. Using 16px as the parent font-size context, give intro an em font-size value equivalent to 20 px.

I am writing the following:

body { font-size: 16px; } .intro { font-size: 1.25; }

Can you please help me? It does not give me the option to skip the question so I can not move on.

Thanks, Penny

Hi Penny, you forgot to add 'em' after the value of font-size.

/* Complete the challenge by writing CSS below */
.intro {
  font-size: 1.25em;
}
